The scouter is a head-mounted device from Dragon Ball Z that is used to measure an opponent’s power level. This real-world version was created by Kier Simmon who says, “I had to collect Scouter language graphics, vector them out, make up a few, turn them into a font, create an animation in fireworks, then bang my head against a wall until it works.”
Now, it won’t really measure power levels, but it does look spot-on with a functioning display. Perhaps if Simmon bangs his head against the wall a few more times he’ll be able to figure out how to make it fully operational.
